Abstract
The utility model relates to a pneumatic brake device for a double-disc friction pressure machine. The pneumatic brake device consists of an operation air cylinder, an electromagnetic switch, an operation rod, a stroke switch, a brake fixing support frame, brake shoes and a brake device air cylinder, wherein the operation air cylinder is connected with the operation rod of a machine tool, the brake fixing support frame is arranged on a cross beam of the friction pressure machine, the width of the brake fixing support frame is greater than the diameter of a flywheel, the installation height needs to be higher than the height of a double-friction-disc main shaft of the friction pressure machine, and the brake device air cylinder is arranged at the upper edge of the brake fixing support frame and is connected with the two brake shoes. The pneumatic brake device is adopted, the beating force in each time of forging beating can be uniform, and meanwhile, the equipment fault rate is reduced.
Description
Technical field
The utility model relates to a kind of pneumatic braking system, refers in particular to a kind of double disk friction screw press pneumatic braking system.
Background technology
Valve blank forging and pressing quality stability is relatively poor, root is that double disk friction screw press hitting power inequality causes, research and develop transformation for double disk friction screw press, increase this equipment pneumatic braking system, 1., the thickness deviation of former forging and pressing product is as 0.3mm hitting power is consistent when guaranteeing to forge at every turn:, now the product thickness tolerance after the forging and pressing only is 0.15mm, and the overall length tolerance is brought up to 2mm by former 5mm.2., reduced material consumption, with convenient follow-up machined, homogeneity of product is protected; 3., the original equipment hydraulic braking, determine and oil pressure height, operator's manual operation, deviation is slightly arranged, and occasional driving screw top flywheel crossbeam occurs and causes device damage.
The utility model content
The utility model purpose: a kind of double disk friction screw press pneumatic braking system is provided, and hitting power was inconsistent when solution forged at every turn, and equipment holds flimsy technical problem.
Technical scheme: a kind of double disk friction screw press pneumatic braking system, formed by operation cylinder, electromagnetic switch, control stick, travel switch, brake fixed support, brake shoe, brake gear cylinder, described operation cylinder is connected with the machine operation bar, described brake fixed support is installed on the crossbeam of friction press, width is greater than the diameter of flywheel, setting height(from bottom) must be higher than two frictional disk main shaft height of friction press, the brake gear cylinder is installed on edge on the brake fixed support, and links to each other with two brake shoes.
Its operation principle is: flywheel is between two friction pulleys.At first start main motor, two frictional disks begin to rotate, during work, click play button, electromagnetic switch action, the inflation of brake gear ante-chamber, piston is regained, and with spring-compressed, brake is unclamped, flywheel is in free state, operates simultaneously the inflation of cylinder ante-chamber, and action bars is drop-down, two frictional disk integral body move to right, left frictional disk contacts with flywheel, and flywheel driven is left-handed, and drift moves down.After drift charges and attacks workpiece, the travel switch action, to operate the air cylinder air source commutation, make the inflation of operation cylinder back cavity, piston moves up, and promotes two frictional disks and is moved to the left, at this moment, right friction pulley contact flywheel, left friction pulley and flywheel are thrown off, and flywheel is turned right, drift is upwards promoted, when rising to setting height, travel switch is sent out signal, and source of the gas electricity taste switch cuts out, upper and lower air cylinders is in free state, frictional disk is got back to the home position, and at this moment flywheel is in the middle of two frictional disks, and flywheel does not contact with left and right sides frictional disk.Simultaneously, brake cylinder is pushed block brake to flywheel under the effect of spring force, flywheel is checked, stop the rotation, drift stops mobile, plays reliable braking action, avoid the abnormal damage of equipment, simultaneously in design process, consider the burst factors such as unexpected outage, by brake cylinder under the effect of spring force, can effectively push block brake to flywheel, prevent the generation of contingency.
Beneficial effect: hitting power is consistent when 1, forging at every turn, and homogeneity of product is protected, and 2, adopt pneumatic braking system, reduced the spoilage of equipment.
